Customer Reviews Merrell Siren 2 Flip

I ordered a size 10 and they were so wide that I could hardly walk in them. They were plenty long so I exchanged them for a 9. They fit much better in the width but are a little shorter than I would like. I'm going to keep them.

They look and fit great but the sole is pretty hard. I was hoping they'd be a little more comfortable. Thus, I give them an average rating.

I normally wear a 1/2 size, medium-width in the Encore and have bought several pair I love. I asked the support team whether I should order up or down in size since the sandals only come in full sizes, and was told to go down in size. Unfortunately, these are too narrow and I have to pay to send them back. Won't be buying any more Merrell online unless I've been able to find and try them on somewhere before purchasing.

Sadly my favorite comfortable & beloved Terran Air Post has been discontinued. The Siren Flip is average but makes a noise when walking that is irritating to say the least. Please please bring back the Terran Air Post Sandal!!

Was disappointed that flip strap on top of foot fit too loose and piece between big toe was uncomfortable. Last years flip was more attractive and fit much better.

The sandal was wide for my foot and wasn't as comfortable as I had hoped it would be.

This is a great looking Flip Flop and fit just as I wanted it to. The downside is the odor. I left them sitting in my laundry room for almost 2 weeks and the odor was still strong. I did return them because of the odor only.

These kill my feet. The toe separator is very irritating. I wish I could return them but I have already worn them a month trying to break them in and it is NOT happening!

I size down a half size for sandals. I must have at least half dozen Merrell sandals, they're generally great, comfortable & stable. These seem loose even though there's a small velcro strap to tighten them up. I've worn them once or twice , don't like the look or feel. Should have returned them.

No arch, no heel reinforcement. Disappointing for a Merrell shoe even for a flip flop.

The Neoprene on the foot bed is the end of the sandal, The sandal does not perform the great way it use to, The foot sweats fast and easily. I do not think it will ever feel the same again. I hope i find a Company that makes them the way you use to make them, I will no longer buy Merrell They are not the same.

I don't like the changes to velcro strap. It used to be adjustable across the entire top of your foot (good for those with narrow feet). Now I cannot purchase this style anymore, my feet flop right out of them. BRING BACK the enhanced adjustability...

I returned these since the shoes are not at all as described!

This sandal could have been a keeper, had it not had such a very bad chemical smell. They would not air out, so I had to return them. I love Merrell, but lately they are hit and miss I feel.
